Great detail in the coloring and shading. I like how the colors interact together to bring the picture out in a three-dimensional look. But most of all I like how much detail and focus you put into the face of the creature in this drawing.
Hah, the real embodiment of a nightmare- or a concept of one, anyway- this looks fantastic, and the bright red in the background really makes ups the fear factor, making this thing burst right out from the screen! The detail in his face is captivating; the humanness in those machine-like embellishments is not only gorgeous but also quite disturbing. Red makes for a highly potent expression of psychological horror, which runs true for the rest of the image. Quite an accomplishment for a 30 minute sketch!
